CASEMENT.

SPECIFICATION forming part of Letters Patent N o. 661,653, dated November 13, 1900.

Application filed November 19, 1897. Serial No. 659,157. @l0 mOde-l To all whom, t ntfty concern:

Be it. known that I, WILLIAM YOULTEN, a subject ofthe Queen of Great Britain and Ire land, residing at 159 Victoria street, Westminster,London,England,haveinvented Improvements in or Relating to Casements, (for which I have obtained patents in Great Britain, No. 23,723, dated December 6,1894; No. 24,171, dated December 12, 1894; No. 4,272, dated February 28, 1895; No. 17,854, dated September 24, 1895, and No. 552, dated January 8, 1896, and in Germany, No. 87,127, dated July 9, 1895,) of which the following is a specification. v

My invention relates to improvements in or connected with metal easements which open both inward and outward, and in order to carry out my invention to either the sides, bottom, or top of a easement-frame I hanga easement upon centers or pivots iu such manner that it may be swung either inward 0r outward.

Between the abutting surfaces of the sides of the easement and easement-frame I provide a suitable weather-check device, such as the device hereinafter described, and I further provide any suitable stay, fastener, and other usual accessories.

Down the stiles of the easement-frame I provide both in the hanging and locking faces, whether vertical or horizontal, pivoted revolving` or partly-revolving rods of a corrugated form in cross-section, fitted in such position that freedom of action is aorded to the easement to move inward or out-ward by a part revolution of the rods, because of the provision upon the opposite abutting faces of the easement of suitably-formed corrugations.

When the easement is closed, the interlocking of some of the cogs on the revolving rod with the corrugat'ions formed on the case- .ment will prove to be an effectual means forV excluding draft or wet.

In order that my invention may be the more thoroughly understood, I Will now proceed to describe the saine with reference to the drawings accompanying this specification, in which- Figure 1 is a horizontal section of my invention as applied to the hanging stiles of the easement and easement-frame. Fig. 2 is a similar view of the locking-Stiles of the easement and casemeut-frame. Fig. 3 is a similar view to Fig. 1, showing the position of the easement when opened inward. Fig. 4 is a similar view to Fig. 1, showing the position of the easement when opened outward.

Thesaine letters of reference are used to denote the same parts throughout the different views of the drawings.

To the top and bottom of the easementframe A the easement A is pivoted by means of pivot-pins b, (shown by dotted circle, Figs. l, 3, and 4,) secured to the hanging Stiles of the easement A, which allows the easement to be swung eitherinward or outward, as may be desired.

Bot-h in the hanging and locking Stiles of the easement-frame A', I provide the corrugated vertical revolving rods C and C, respectively, preferably extending from the top to the bottom of the easement, and in like manner in the abutting faces of the easement A, I provide for a series of vertical corrugations into which the corrugations on the revolving rods may snugly tit when the easement is in the closed position.

From the foregoing description it will be seen that when the easement is opened either inward or outward the corrugated revolving rods C and O', pivoted in the hanging and locking stiles of the easement-frame, are actuated by the adjacent corrugated faces of the easement (marked 4 and 6) rotate, and thus permit the easement to turn freely, and upon revolving the easement back again to the closed position the interlocking of the corrugated faces of the easement and revolving corrugated rods makes a perfectly weatherproof joint, as shown at`4, 5, 6, Figs. l and 2.

The corrugated face of the hanging stile of the easement A is as of the form of a segment of a circle described from the center of the dotted circle b, Fig. 1, so that the easement may turn in the concave portion formed in the easement-frame A@ Y Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In aswingingcasement, the combination of a easement-frame, a revolving corrugated rod mounted within said easement-frame, a easement pivoted to said easement-frame,eor

IOO

ing and locking Stiles of said easement and running the length thereof and adapted to interlock and form a Weather-tight joint With the corrugated surfaces of the said corrugated revolving rods, substantially as described.
